Infinite scroll has been called autopagerize, unpaginate, endless pages. But essentially it is pre-fetching content from a subsequent page and adding it directly to the user’s current page.
When a user scrolls towards the bottom of the page, the next page of posts is automatically retrieved and appended. This means they never need to click “Next Page”, which dramatically increases stickiness.
Features:
<ul>
<li>Works out-of-the-box for many popular WordPress themes — just activate the plugin and scroll</li>
<li>Fully customizable to adapt to your site and theme</li>
<li>Requires no (hopefully) template hacking, only a knowledge of CSS selectors.</li>
<li>Relies on shared database of common themes to simplify installation process</li>
<li>Maintain local database of theme presets for all installed themes (shared across network on multisite installs)</li>
<li>Countless API endpoints to modify the behavior.</li>
<li>Backwards compatible: Will not break RSS readers, mobile devices, or browsers with javascript</li>
</ul>

In addition to normal infinite scroll behavior, this plugin adds infinite scroll to the single post page. When reading a single post, once the reader reaches the bottom of the page, the next post loads in. This is similar to functionality on big news sites such as Time.com, LA Times, Quartz, Vogue.com
The default WordPress TwentySomething themes, Genesis themes and Canvas themes are already compatable with this plugin and ready to go!
Relies on add_theme_support. If your theme is not in the above list, add the folliwing to your themes functions.php file: <code>add_theme_support( 'infinite-transporter' );</code>
See installation and FAQ sections for more on getting set up.
